DISPENSING DEVICE.

Application filed September 2, 1922. Serial No. 585,987.

To all whom it may concern:

Be it known that I, FRANK MoLAUGHLIN, a-citizen of the United States of America, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Dispensing Devices, described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The principal objects of the invention are,

to provide a form of container of simple and cheap construction which may be easily and quickly attached to the brush head so that when empty it may be detached and discarded, and to devise a structure which will enable the user to accurately regulate the amount of soap dispensed from the holder into the brush thereby avoiding waste. v

The principal features of the invention consist in the novel construction of the container and brush head whereby said brush head is retained in its operating position upon the soap container through the medium of the plastic soap in the container, and whereby the brush head is held from accidental turning by a spring ratchet contact carried by said brush head and engaging a ratchet surface of the container.

A further important feature consists in the novel manner ofindicating the relative turning of the container in respect to the brush head.

In the drawings, Figure 1 is a perspective view of a brush constructed in accordance with this invention.

Figure 2 is a perspective view of the soap container.

Figure 3 is a perspective detail of the brush head and spindle with the associated parts separated and arranged to show their detailed structure.

Figure at is an enlarged longitudinal sectional view of the brush.

Figure 5 is a cross sectional view on a reduced scale through the line 5-5 of Figure 4.

Fountain 'shaving'brushes have been devised in various forms but these devices have been subject to many detrimental conditions particularly where cartridges containing the soap are utilized because, of the CllStI1bl1t1ng ,elei'nents becoming clogged with soa and accumulating dirt which cannot be c eaned out. Furthermore, the cost of such devices is prohibitive for general use and it is the primary purpose of this invention to produce a structure which will enable the brush head to be separated from the soap container in such a manner that they may be thoroughly cleansed, the container when empty being entirely discarded the same as an empty can.

A further and very important object; in accomplishing the above is in thenovelty of utilizing the soap material within the con tainer as the active means for holding the brush head in place thereby greatly simplifying the construction.

In the construction herein shown the bristles 1 are secured within a ferrule 2, preferably formed of sheet metal having a threaded outer wall 3 and an inner tubular stem 4. A locking ring 5 is shown inserted over the inner stem 4 and secured-by. the stem being flared outwardly at the upper edge 6 and hold the bristles securely-.

A cylindrical member 7 preferably formed with a knurled outer face has a reduced portion 8 which forms a shoulder 9. Upon this reduced portion and abutting the shoulder 9 is an inverted cup-shaped ring 10, the inner wall 11 of which fits tightly upon the reduced portion 8. This ring maybe pressed into place or may be soldered to the portion 8 if so desired.

A rectangular hole 12 is cut through the inner wall 11 and the portion 8 close to the bottom to receive a ratchet roller 13 which is mounted ona spring wirevcollar 14 encircling the portion 11. I The roller 13 is adapted to extend inwardly through the hole and is free to spring outwardly for a purpose which Will hereinafter appear.

A threaded sheet metal cup-15 fits snugly within the cylindrical member 7. and is adapted to receive the threaded ferrule 2. This cup is provided with a central tubular stem 16 which is spaced from the inner wall of the stem 4 of the ferrule 2 and upon this stem 16 is mounted a rubber tube 17 which fits between the two stems. The upper end of the rubber tube is thicker than the lower portion and is moulded with a closed outer end 18; This outer end is slit longitudinally for a portion ofits length. Thethicli wall of rubber holds the edges of the slit closly'in coiitact except when pres sure is applied tram the inside to force the,

which the soap is adapted to pass. A small depression 23 is formed in the centre ot the member 19 and in this is fixedly secured the head of the threaded spindle 24! thus operatively connecting the spindle with the member 7. This composite structure forms .the complete brush head.

V It will be readily seen that this structure can be easily cleansed whenever desired.

The container herein shown consists of acam structure 25 ofcylindri eal form which is provided with a rim 26 lock seamed in place. .Thisjrim is'depressed within the can and is formed with an upturned flange 27 spaced from the outer wall. A cap 28 is placed over the flange 27, the bottom edge thereof resting in an annular recess 29 in the run.

The side wall of the cap is formed with.

a plurality of vertical slots 30 which form a: ratchet surface engaged by the ratchet roller13 extendin through the hole 12 in the ring 10 and member 8 which engages the outer wall of the cap 28 in a turning fit. The top of the cap 28 is depressed inwardly and swaged outwardly at 31 to en gage in looking contact with anedge flange 32 at the top of the flange 27 of the rim 26. Holes 33 are formed in the cap'QSto allow the passage of soap therethrough, and a central hole 34. is provided to allow the insertion of the spindle oi the brush head. ithin the can is slidably and non-rotatively arranged a piston 35 which isthreaded to receive the spindle 24. The container is filled between the piston and the cap with the plastic soap and the holes in the cap are covered with a suitable removable disc. The container'thus provided is a unit which may be sold independent of the brush head.

The'bottom 36 of the container is lock I seamed to'the side wall and is formed with a central depression 37. ithin this central depression 1s rotatably arrangedan inverted gsheet metal cup 38 which has a central depression 39fthrcaded to receive the end of ;the spindle ofthe b rush head. A spring wire lO is secured to the top of the cup 38 by clips .41 pressed from the cup and extends outwardly into contact with the inner side wall of the container.

' 'The container is formed with a vertical SGZUlljWlllCll llOlClS the piston from rotation and the spring wire 40 engages this seam when the spindle is turned to rotate the cup 38. The spring slips over the seam wit-h a resonant click when thespindle is turned to the right to cause the piston to press against the soap, so that the person using the brush will have a clear audible indication of each revolution of the brush head in respect to the container.

In the use of this brush, the brush head and spindle are separate from the container which is sealed in the manner described and upontheremoval of thesealing disc from .the swag-ed depression 31 in the annular recess 29, the spindle is inserted through the central hole 3% and pushed down through the soap until it enters the threaded hole in the piston. The brush head is then turned to thread the spindle into the piston and continuing therethrough the spindle enters the threaded recess in the inverted cup 38, turning into said recess two or three threads and then locking so that the cup 38 turns with the spindle and brush head.

Thebrush head is then turned so that the spindle forces the piston upwardly until the soap is forced up through the holes 33 in the container cap and through the holes 22 in the member 19 and up into the central tube and rubber tube "until the pressure spreads the split end of the rubber tube apart. When the pressure is discontinued, the soap ceases to flow and the elasticity of the split rubber tube is sutiieient to close it off. The brush is then ready for shaving. In inserting the brush head in place, the ring 10 fits into the depressed rim of the can in an easy turning fit, the reduced portion 8 of the member 7 fitting closely around the slotted 'cap' 28 and as the brush head and container are turned in relation to each other, the ratchet roller drops into theslots and holds the brush head from turning back-'- wards while the brush is being used in lathering. The spring ratchet will of course easily yield to the turning action of the hands as also does the spring wire click member 450.

The proportion of the parts is se arranged that one turn of the container will force enough soap out of the feed tube for one shave.

hen the piston has been tightened into contact with the soap it forms theactive means for holding the brush'head in the container and no definite mechanical means is required as 'the piston is positively connected to the brush head by means of the spindle and the soap engages the rim 26 of the can. When the piston reaches the top of the can he brush head may be turned backwardly and in two or three turns the spindle releases itself from the 1nember-38 which canllO not turn backwards as the spring acts as apositive ratchet. The brush head may then be spun out from the piston and the container may be thrown away. The spindle and brush head may be washed off if desired before insertion in another container.

It will be readily understood from this description that the actual construction of the brush head may be varied to a very considerable extent as also may the construc tion of the container without departing from the spirit of the invention.
